From undersized to oversized

The production of big and small parts intrigues me. The reason is because making an unconventionally sized part requires an extra dose of manufacturing know-how.

Extra thought must be given to handling oversized parts, for example, to prevent them from toppling and injuring operators. And large−often asymmetrical−workpieces can be difficult or impossible to mount on machines.

Smaller parts also pose workholding challenges. Typically they are too small to incorporate surfaces suitable for securing them to a machine. An additional concern is gripping force. Even the smallest amount of overgripping torque can damage a tiny workpiece.

My interest in oversized and undersized stuff extends to 3D-printed parts.
